This picture shows how the oil flow path is controlled. The arrow points to a dowel plug in the block. On this engine, the oil lines are plugged off and the dowel is in the "out" position - flush with the block surface. When the filter and hoses are installed, this dowel must be hammered into the block. That diverts the flow
out to the hose fitting just below. Use extreme care doing this - hammering on a frozen plug can crack the block.
